Power, Water and Space
Most trailers need power from an outlet or a generator, level ground, room to tow in and set up, and some need a water connection. Steps are not accessible; ask for a lift or ramp, or add an ADA unit beside the trailer.
In the 15 listed places averaging 20+ inches of snow, the tow path and pad need plowing before delivery and pickup.
Who Handles Local Rules
For a restroom trailer parked on a public street or in a public lot, or set up for an event on public land, the government to ask depends on where the site is. Of the 181 listed Maryland places, 34 are incorporated, 147 are unincorporated Census-designated places. In an incorporated place, ask the city, town, village or borough; in an unincorporated community, ask the county. We don't say whether a permit is needed; each city page names who to ask.
What to Ask For
- Number of stalls for your headcount
- Power the trailer needs and who supplies the generator
- Whether it needs a fresh-water hookup
- Room to tow it in and level it
- Steps vs a lift or ramp for accessibility
